Ender 3 Circular air flow Guide

thingiverse

The existing airflow guide on the hotend head simply doesn't provide enough airflow from the right side, which can lead to cooling problems with certain types of filament. To address this issue without altering the stock appearance or relocating any fans, I came up with a solution by myself. This new guide is essentially identical to the original one but features an extended circular path for the air to flow smoothly around the nozzle in a circular motion.
